Bertrand Delacretaz commented on SOLR-69:
-----------------------------------------
> Is there a way to get this patch to listen to start & rows on the
> moreLikeThis result section?
IIUC you want to use the start & rows request parameters to limit the number of
results in the moreLikeThis section?
This is not implemented currently, and if we did it we'd have to use different
parameter names (mlt.start and mlt.rows maybe) so that they don't interfere
with the "main" part of the result set.

> Here's a patch that implements simple support of Lucene's MoreLikeThis class.
> The MoreLikeThisHelper code is heavily based on (hmm..."lifted from" might be
> more appropriate ;-) Erik Hatcher's example mentioned in
> http://www.mail-archive.com/solr-user@lucene.apache.org/msg00878.html
> To use it, add at least the following parameters to a standard or dismax
> query:
> mlt=true
> mlt.fl=list,of,fields,which,define,similarity
> See the MoreLikeThisHelper source code for more parameters.
> Here are two URLs that work with the example config, after loading all
> documents found in exampledocs in the index (just to show that it seems to
> work - of course you need a larger corpus to make it interesting):
> http://localhost:8983/solr/select/?stylesheet=&q=apache&qt=standard&mlt=true&mlt.fl=manu,cat&mlt.mindf=1&mlt.mindf=1&fl=id,score
> http://localhost:8983/solr/select/?stylesheet=&q=apache&qt=dismax&mlt=true&mlt.fl=manu,cat&mlt.mindf=1&mlt.mindf=1&fl=id,score
> Results are added to the output like this:
> <response>
> ...
> <lst name="moreLikeThis">
> <result name="UTF8TEST" numFound="1" start="0" maxScore="1.5293242">
> <doc>
> <float name="score">1.5293242</float>
> <str name="id">SOLR1000</str>
> </doc>
> </result>
> <result name="SOLR1000" numFound="1" start="0" maxScore="1.5293242">
> <doc>
> <float name="score">1.5293242</float>
> <str name="id">UTF8TEST</str>
> </doc>
> </result>
> </lst>
> I haven't tested this extensively yet, will do in the next few days. But
> comments are welcome of course.
